Hey guy's!!
I stumbled on this site trying to figure out what kind of rods to use for welding a(cracks) on the starter mount,(outside dog ear mount).
I knew you could weld engine blocks,but i'm left confused on weather to use a low,or high nickle rod. The engine block is a 010 block,i think that's the higher nickle blocks.??? Anyways i know the procedure on doing this,i just need a few opinions on the welding rods.

p.s. i've heard of people using 55rods, is this too soft?? thanks for the help.
